PLT / PLR
NBFM Multi channel Data Packet Link Radios
Inexperienced users of ISM band radio modules often
require a totally transparent interface. This can require
considerable processing power, and buffer memory,
to be provided in the radio device.
The more experienced user, on the other hand, may
not want to write a raw radio interface, but desires a
module that gives more control over the datastream
than a 'beginners' solution.
The PL radios represent such a compromise solution.
